I have tried RRA triggers and fancy single-stages, and I actually prefer the Armalite "Tactical Two-stage" triggers. I put them in both of my precision builds. It has a smooth first stage with an easy pull, an obvious stop point that you can sit there all day holding the trigger at, and a clean second stage/break.
The RRA trigger I tried was way too touchy and had no obvious stop - just pull lightly, and BAM. I sent it back and got another Armalite. You can get them for ~$100 or ~$130 with an entire LPK.
